Cox Communications is one of the largest cable TV providers in the US and has recently committed to rolling out ultrafast broadband internet service for residential users. Cox will be rolling out gigabit speed broadband to all of its residential customers starting this year. Cox plans to invest hundreds of millions of dollars in the rollout of the faster service.

Cox is starting with upgrades to its networks in Phoenix, Las Vegas, and Omaha, Nebraska. The first customers in those areas will be able to upgrade to gigabit speeds in Q4 2014. Cox is the third largest cable and internet provider in the US behind Comcast and Time Warner.

Currently the fastest internet speeds offered by a cable provider to residential customers is 505 Mbps. Gigabit speeds will nearly double that fastest current offering. Cox's new network speeds are much faster than the average connection speed in the US, which is currently around 10 mbps.
